Hi I'm having a hard time finding the brown wire for switched 12v. Did you splice into the blue diagnostic connector below the rear air vents to find the brown wire?
its brown/blue on one side, converting to black yellow on the other. I connected to the black side as it was easier to tap into but electrically its the same circuit. BTW, when you take yours apart take a picture for me of the black/yellow end when it runs to. it looks like it had a rubber cap over it so im not sure it was ever connected to anything at the end, but it was just hanging when i opened the vents. I triple checked, my remote wire still is functioning as intended, as is my seat sensor and center console light, so in all honestly it may just be an used connector but i want a point of reference and there are very few pictures of this on google :-(
